Hey guys, hoping for some advice...I'm looking to port my number to a non-Voda PAYG sim, from my current Voda contract, then back again on a new Voda contract whenever the N900 is available in Nokia high street stores. Question = what network would be best if I were to go into say an O2, Orange etc high street store, ask for a PAYG sim and port to it and then be QUICKEST to give me a PAC code to request porting from, back to Vodafone? Also, who does free ones? Obviously don't care about tariffs, I just want to use it as a stop-gap
