Hi there

we have just got back from the UK, and I'm trying to get my wife's phone working. She has a 4S with iOS6 on it (doesn't want iOS7 yet, but that might be inevitable).

I have a fairly old XT sim in it (2 years or so?). It's on prepaid, and it has credit. I bought a 500MB data pack for it the other day.

With the sim in, it's showing 3G, bars etc, and calls/sms work fine. If I tether it over USB, that works fine, I can ping and browse ok, if a bit slow.

But nothing else works. The browser just times out eventually, other apps are the same, there is nothing in the logs from xcode. No "you are not connected" messages, just long timeouts. It's like there's a firewall up... but it doesn't have one....

Anyone got any ideas? I can't change the APN 'cos its locked out, only the APN for tethering. I thought I might have changed the SIM setting thing for roaming, but it matches what I have. If I change that from TNZ to Sponsor, it doesn't work at all. I'd rather not do the backup-restore-restore the backup dance, 'cos then she gets iOS7....

Very frustrating :)

Thanks!

Nic
