Apple insider is reporting that O2 will open it’s stores early on the July 11th iPhone 3G release date to sell the 3G Version of the Apple Iphone.

O2 is also said by the new sources to begin stocking up on iPhone 3G units the week before the launch rather than the just-in-time deliveries that were made in some areas with launches of the original Apple cellphone. Demo units may be in use shortly afterwards, according to the sources.

For some, 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 PAYg phones after 12 months will remain true for iPhone 3G.
