iPhone APN Changer

Hi – I have an Iphone 3Gs under a Samsung phone account with AT&T here in the US. I wa able to use your fix last year and access internet and email on my 3Gs phone without having to purchase the data plan. Problem is I just upgraded the 3Gs phone to Iphone OS4 and now am screwed. Lost all my internet capabiities and have no email access anymore. Web apps don’t work either. Please help. I know you are working on a fix (thank you) but until you do, can you help me uninstall 4.0 and go back to my 3GS so at least I can use my phone with email and internet apps.

P.S. Can’t load your latest fix and test for you as I can’t seem to get access to any WiFi at this point either? Ugggh….I am so bummed out

I installed your US AT&T profile and it installed fine and USB connect is good but when it tries to grab an IP it is limited with no web connect.
Help please

Since I upgraded to os4, as some of you cannot, I cannot use internet through cellular network anymore.
When I was running on os3, i had created a profile with iPhone configuration tools.
This tool is the only way to’configure proxy settings under cellular network(APN)
Now when I upgraded to os4 this profile disappeared, even though the
APN info is still there, but now I’m sure the proxy settings isn’t.
So when I try installing back the profile this is the error Message I get: Only one APN configuration can be installed at a time…….
I know the restore to new phone will work, because it allows me to reinstall successfully the profile, BUT doing so I loose all personal data such as SMS .
If I make a restore from backup I face the same problem again…..to me it seems a h**l of a bug!!!
Any ideas to solve the problem and keep personal data?
Any reply is highly appreciated!
Thanks
