Based on comments esp. by freefall this should be fixable, maybe only on kernel level, maybe in applesaft (of course applesaft would be better, kernel needs programmer to reflash). Seems T-Mobile is using some rarely used (actually we never heard anybody else using it) function related to download type of sms and it seems we don't handle this properly in kernel. Not sure, haven't seen it, just speculation, so far the reports are mixed and maybe it's something completely different.

Hi All

I have had the same problem. I find that the phone may works on T-mobile perfectly ok for a couple of days. The problem really started on Saturday night 20/01/08. I got a new sim card on Sunday, it was ok for a couple of hours and then signal went again. But however from Monday until Tonight (tuesday) evening the problem started again. By the way I have never used edge on my phone. I depend on wifi. Crying or Very sad

Any furtrer feedback would greatly appreciated!!!!

Thanks

I suspect that T-Mobile see who connects his mobilphone with and wihout iPhone-Contract. So the T-Mobilesystem decline after 3-4 minute the connection.

Can anybody having these issues try http://www.bladox.com/pub/applesaft-0.92-tmob.tar.gz ?

It's a dirty hack suppressing SIM PP_DOWNLOAD SMS service in EF_SST file. It's based on hypothesis that T-Mob is sending such messages to SIM card and there is some app installed answering special rarely used way, which we probably badly handle in kernel. So this applesaft level hack says phone (iphone) - hey, I'm SIM card which doesn't know such messages and phone/iphone sholdn't pass them to SIM at all. Tested on some phones (not iphone) and it works, such messages are stored in normal SIM memory and visible to user (garbage).

So it's open:
- if the TM issue is really this
- how does iphone handle such SMS

Please test.

There would be some drawbacks of this applesaft hack:
- some SIM/Turbo apps may not work - those using such SMS_PP_DOWNLOAD and those services we don't allow in EF_SST and are not allowed on SIM (probably e.g. CALL_CONTROL need for callback app).
- user will probably see such SMS as garbage - may be interesting to see when TM is sending it

But both are minor if it makes iphone stable.

Please report.

Will this fix only work for T-Mobile? I believe my girlfriend is having the same problem here in India with BPL. Every 30 minutes, it loses signal for about 1 minute.

Do you think this will work for India BPL?

Has iPhone been officially released in the UK yet? If that is the case, I am getting the distinct impression that UK and now Australian Mobile carriers are altering their networks to shut down the xSIM users, as a lead up to launching iPhone officially for their own networks. Forcing some to buy a brand new iPhone.

Thank you, although I wouldn't consider it a conspiracy theory. It just seems like dodgey business practices. It might border on bad ethics, but its arguable.
