Roaming onto T-Mobile in the USA has caused untold problems

I have been New York - Manhattan since last Wednesday.

On arriving in the USA my iPhone roamed onto AT&T 3G - no problems - amazing service! Blistering fast internet, Maps work like a dream & all my apps running smoothly.

On Thursday night went o a club with poor reception. My iPhone roamed onto T-Mobile, then the pain began!! User uploaded file

The signal on my iPhone now continuously fluctuates from 1 bar to full reception every 5 seconds. What I mean by this is that I get 5 bards for a split second then 1 bar for aprox 4.9 seconds. This in tur is causing the iPhone to crash aprox every 3 or 4 minutes.

If I'm not a WiFi network I get the error "You Ae Not Connected To The Internet" when trying to use any app which requires a connection. In addition if I try to send a text message I get the error message "Error Whilst Sending Message". In addition, I have had friends calling me asking why I'm not responding to their texts, so obviously I can't receive texts too User uploaded file

I have repeatedly tried to roam back to AT&T, but every time I go into the networks screen in System Preferences I get the error "Unable to Load Networks List".

I then restored the iPhone to original settings using iTunes, but agin it jams onto T-Mobile immediately and won't give me the option to switch.

I have tried to restore the iPhone to at least get my contacts, mail etc back, but every time I try to sync the iPhone to perform a restore, it crashes. The crashing seems to take place during the network signal fluctuation.

Being quite a logical person I appreciate that this can't be a hardware fault as it worked fine on AT&T, but it seems that there is a problem with the iPhone holding a connection with T-Mobile. In addition, trying to maintain the signal is probably pushing the processor so hard it is causing the iPhone to crash repeatedly.

In addition, I tend to travel a lot. In an average week I'm abroad aprox 3-5 day roaming onto other networks & I've never had a problem with my iPhone 3G.

As you an imagine I'm now getting quite desperate.

So, the point of this post is 2 fold.

1 - Has anyone else experienced a similar issue when roaming, T-Mobile or not?

2 - Can anyone think of a solution to this problem?

Any help, advice or suggestions would be greatly received as I can't bear the thought of having to que at the Apple Store on 5th Avenue on a Sat afternoon to try to get to the Genius Bar....

I just flew into NYC from London (O2) on Saturday and have been experiencing all the issues detailed below.

Roaming on T-Mobile, fluctuating bars/reception, regular crashing, unable to load network list, etc.

As the comments suggested, I can access AT&T in the network list only if I disable 3G and Data Roaming and reboot -- but that's extremely limiting/annoying!

I have the iPhone 3G v2.1 (5F136). I have been to NYC two other times for 1-2 weeks each time over the past two months and have never experienced a problem. I don't think it's the iPhone software because that hasn't changed. Am guessing it's an issue with the AT&T network because if I enable 3G and Data Roaming AT&T disappears from my network list and I'm forced to edit the network settings.
