UK iPhone users: What network will you migrate to?

o2’s network errors aren’t doing them any favours given they apparently lose their UK iPhone exclusivity deal on the 9th of October.

Which network is going to be your operator of choice for iPhone?

3? Vodafone? Orange? T-Mobile?

I’ve already got a ton of devices on my Vodafone contract so adding an iPhone 3GS would be quite easy and I really do find Vodafone’s data network to be highly reliable.

Or, will you be staying loyal to o2?
