Hey looking for some help, I got my phone on launch day and been working fine, until I went to the states with work and came back today! Every time I open Facebook, maps, twitter my signal drops out and searches for network then comes back after about 1 minute! I've tried rebooting the phone re installing the apps etc but nothing working? I'm on the O2 network in the UK, anyone had similar probs? ---------- Been playing about and seems to be doing this whenever location services are on?
