Auto disconnect GPRS/3G on Samsung i780

I recently bought a Samsung i780 which has Windows Mobile 6. There is a tiny bit of a problem specially with the GPRS connection. Everytime the mobile checked my email it would keep the connection alive and would not disconnect. Since it remains connected it drains out the battery.

You will need a registry editor to make these changes. You can download a free registry editor from http://www.phm.lu/products/PocketPC/RegEdit/. Download the Pocket PC 2002/2003 (ARM/PXA) version and install it on your mobile phone.

To change the settings follow the detailed steps listed on this page. I have listed the steps in brief. You will need to use the registry editor to make the changes.

HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\

The 1st key is DWORD CacheTime the number denotes the number of seconds to wait before the auto disconnect, by default it is 600 seconds.

the 2nd key is Multiline value / String SuspendResume which can have 2 values

~GPRS! :- 3G always On
GPRS_bye_if_device_off :- timeout after CacheTime

On my phone it was set to ~GPRS! due to which the connection was never terminated.

Thanks! that was great but I had to change it back to ~GPRS because my skype was disconnected after the specified time.

I'll stick to the manual option of disconnecting the GPRS. i.e. in the comm manager "Disconnect Cellular Data" :p

But that is a one good hack.

The best mobile development platform for hobbyist programmer

This is something I have been thinking for a while so here it goes. This is a list of platforms I know of and my choice of what makes sense for a hobbyist programmer like me. Let me first list down all the possible platforms and then list down the pros and cons that I feel are associated with each platform. Java ME (The platform formally known as J2ME) Windows Mobile Linux Palm Brew Symbian Blackberry iPhone iPhone Let me start with iPhone the darling of the media and blogger's till about a fortnight. I had real expectations from iPhone as a platform but the way its been going so far I would never bother developing for it. Officially there is no SDK with which one can build applications. What ever tools the community had built have been rendered useless with the iPhone 1.1.1 software upgrade . The community might be able to hack a version for 1.1.1 but without any support from almighty apple its just a cat and mouse game. With every minor release the applications

Airtel 16Mbps for Impatient Ones

This advert can be the summed as the best in terms of making fun of the impatient ones. The new Airtel broadband is 16 Mbps but with a slight hitch. At Rs. 2999/- with a Data Transfer Limit of just 20 GB. Just listening to a few hours of music videos on Youtube should be enough to exhaust the limit in no time. Thinking of downloading torrents is something one should not even think about. Not sure who Airtel is targeting with this plan. If you bought this plan do leave a comment.
