iPhone 2G on T-Mobile -- Anybody experiencing SMS loss?

[Razor1973]

I am using a freshly jailbroken and unlocked iPhone 2G on 2.2 with my T-Mobile account. However, I have been having a lot of trouble with text messages, namely people not receiving half of the ones I send. I seem to be receiving all, but my friends can't say the same.

If I go to Settings > General > Network > Cellular Data Network, these are my settings:

APN = epc.tmobile.com
Username = <blank>
Password = <blank>

Has anybody else experienced these problems? And if you aren't, are your settings the same as mine?

Thank you.

P.S. I also have a T-Mobile G1, so my data plan is the unlimited all G1 plan, in case that makes a difference.

i am on tmobile and am having no problems, i use wap.voicestream.com. I used epc.tmobile.com in the past and had problems losing data when i launched safari so i went back to wap.voicestream.com and have had no problems since.

As someone recommended, I installed jailbroken 2.2.1 to start fresh and see if that solved the problem. It didn't. Half of the SMS's I send from the iPhone still aren't received, whereas everything I send from my G1 seems to reach its recipient. This is the one reason I have been having no choice but to use the G1 more than the the iPhone.

One report here:

Yesterday my colleague sent me one and I did not receive at all.

Then he tried one more time and it worked, but I do not like the idea that some of my SMS are being jammed.

I'm on 3.1.2 and having the same issue too. Has anyone found a fix for it?
