  • Upgrading the iPhone 3GS to iOS 6.1 while preserving baseband using Jailbreak; a Flowchart

    Date: 2013.02.13 | Category: Mobile | Response: 0

    The following flowchart intends to simply the complex procedure of upgrading an iPhone 3GS (new bootrom) to iOS 6.1, while preserving the baseband (modem firmware), so that it can be SIM unlocked once it is jail-broken.

    Please use at your own risk, and consult Vinod Yalburgi’s post for further details. It is also possible to use redsn0w 0.9.15b1 instead of sn0wbreeze 2.9.8, but sn0wbreeze 2.9.8 is highly recommended because it automates the creation of the custom firmware, the jailbreaking and the hacktivation. In addition, using redsn0w 0.9.15b1 resulted in the device being stuck in recovery mode.

    Note that the flowchart below cannot be direct-linked from this website. For direct-linking, you will have to use this image url, which links to a higher quality flowchart.

  • Why do Western countries pay stupendously more for prepaid wireless service?

    Date: 2011.02.12 | Category: Mobile, Trends | Response: 0

    While Canada is home to latest developments in wireless technology (Blackberry is headquartered in Canada), wireless service in Canada features a huge price disparity compared to developing countries.

    For example, Rogers Wireless, the biggest mobile phone service provider in Canada, has several prepaid plans. The prepaid plan that requires the minimum top-up ($10/month) charges 40 cents a minute for incoming and outgoing calls.

    On the other hand, Vodafone India minimum top up for a prepaid plan is $1.42/Month (66 Indian Rupees) and the rate offered is $0.01297 cents a minute for outgoing calls. Incoming is free. Interestingly, Vodafone UK offers 33 cents a minute (21p) for outgoing calls.

    We are told that this disparity is the result of economies of scale, given that it is impossible for Canadian wireless service providers to find as many subscribers as they would find in India. But there are many more reasons to think otherwise. The wireless service industry in North America is concentrated among a few players, just like Big Tobacco and Big Sugar. There maybe more at work here than economies of scale.

    Why do we pay more?

  • Blackberry Waiving $200 Registration Fee for App Developers for “Limited Time”

    Date: 2010.12.27 | Category: Mobile | Response: 2

     

    Blackberry has been late to the apps marketplace. This was partly because apps were never a main focal point for RIM. But after some growing pains, the Blackberry App World now provides an app marketplace for Blackberry users that bears the robustness we have come to expect from the Blackberry OS. It still requires PayPal for purchasing apps though.

    Recently, I came across this message on the Blackberry App World Distribution Page:

    BlackBerry App World limited time offer: $0 registration and submission fees.

    Obviously good news for developers. Given the fact that the one time registration fee costs around $200.

    Maybe RIM has learnt that penalizing charging developers is not a good idea at a time when apps are becoming critical to the success of mobile phone platforms.

  • Which smart phone OS gives the best local PIM synching?

    Date: 2009.11.21 | Category: Mobile, Reviews | Response: 2

    For many people, a smart phone also doubles up as a personal information management (PIM) tool. A typical smart phone is expected to have at least an address book, a calendar, email storage and the ability to configure alerts and reminders.

    Many students and employees also use their email client software as a personal information management tool on their computers. Such smart phone customers want their smart phone to wholeheartedly synchronise with the personal information management software on their computer. But here’s where the limitations of the smart phone OS, the computer OS and the computer email client come into play.

    This table is meant to compare the PIM synching capabilities of different smart phone OS’s across different platforms and different email clients. Please note that PIM synching is different from a backup. A backup produces a single fat file that is meant to restore data back to the phone or another phone, in case the original is stolen. Also note that it is possible to carry out PIM synching using third party software not supported by the phone manufacturer, in addition to various hacks and tweaks. But this table is limited to computer software provided by the phone manufacturer. Because the aforementioned alternatives are generally beyond the means and capability of the average user.

    Online PIM synching that uses the cloud computing model is included in the table for reference purposes. In some cases, online PIM synching can in turn be synched with a local computer application. For example, An email message on a Windows Mobile smart phone can be synched with a Microsoft Exchange server via ActiveSync. And an email client on a Linux computer can download the message. Or, a calendar entry on a Blackberry can be synched with a Lotus Domino server and a Windows computer with Lotus Notes can download the calendar entry. Or, a contact entered into an iPhone can be stored online through the MobileMe service. And an Address Book on a Mac computer can connect to the Internet and download it. But unless the smart phone OS manufacturer specifies that this can be done with a particular program for a particular operating system, it will be considered unsupported and will not be given a check mark. Our focus is on one step PIM synching with a local computer (docking), which I consider true PIM synching.

    Some smart phone OS’s allow direct synching of files stored in the phones internal or external memory every time the phone is connected to the computer. But in most smart phones, these files are meant to be manually copied to the computer.

    Please note that the specifications listed in the table are based on a cursory review of information on the manufacturer’s website. Errors and Omissions are very likely (And I would appreciate if you bring them to my attention). In order to verify for accuracy, we did try to contact the manufacturers before publishing this post. This table is no substitute for an exhaustive analysis involving actual lab tests. And the specifications listed below tend to change by the month. Please consult the manufacturer before making any critical decisions.

    The table below indicates online PIM synching that in turn can be synched with Desktop applications (where officially supported by the manufacturer). Please note that with the exception of the Blackberry Enterprise server, online PIM synching is done through unencrypted transfers via the Internet. Cloud computing has its dangers.

    Conclusion

    The iPhone OS gets commendation for its versatility. Apple has done an uncharacteristically good job at reaching out for the needs of non-Apple users.

    Windows Mobile is still trying to stick to Windows, and is truncating its user base in the process. And in typical Microsoft boorishness, Windows Mobile will only synch PIM information to Microsoft Office Outlook (NOT Windows Live Mail or Outlook Express). Mind you, Office Outlook is not included in the economical student edition of Microsoft Office.

    RIM OS is emerging as a force to reckon with, considering the fast developmental response of the people at Blackberry. Let us not forget that this is a relatively new company. I would not be surprised to see RIM OS to be the first smart phone OS to offer PIM synching compatibility with Linux, in the near future.

    Other small players have tried to sidestep local PIM synching by wholeheartedly adopting the cloud computing model. Cloud computing has its risks.
