Page 1 of A couple of dumb questions.....

My son would like a K700i PAYG on O2. The chapest deals i can find are on either Virgin or Vodafone......

Question 1 - "Would it be recomended to buy cheaper on either of these networks and get the phone unlocked? Although i heared that Vodafone disabled the use of mp3 as ringtones... Would this still bethe case if it was unlocked to 02?"

Question 2 - "I`ve also heared that Tesco Mobile piggybacks the O2 network... Thus, would a Tesco phone have to be unlocked to 02 or not?

Many Thanks in advance for for your responses
