AppleInsider has reported on a rumour that the official British carrier of the iPhone O2, will be unlocking 3G iPhones for a nominal charge of £15 after 1 year of service.

For some customers, though, the most important news may come a year later. Separate O2 staff are suggesting that the wireless carrier’s usual policy of offering an unlock code for Pay As You Go phones after 12 months will remain true for iPhone 3G.

No statement from the company can be found on this issue so far and the sources are also unnamed. This little nugget of information will remain marked as just another rumour for now.
