Hi All I'm hoping someone can help. I've got a San Francisco. Unlocked it using the IMEI method. Inserted my O2 sim, connected to my home network and everything was working great. I upgraded to Froyo 2.2. Have internet access, signed into my google account through YouTube but cannot access the market. I get : Attention! An error has occurred. Please try again later. I have added the o2 vpn settings. The guide says you need to connect to the market through 3G. There is no option for 3G. From Mobile Network Settings > GSM/UMTS Options > Network operators I have tried O2 and 3UK. Someone with O2 must have got this working. What am I doing wrong?
