They are all sort of similar these days mate, the only thing i would say is watch the ones in tha papers as most of them are 18 month contract now cos of the price of the phones.

Best bet is decide what phone you first then take it from there.

I changed to 3 six months ago and have had no problems at all.

It is becoming a nightmare these days though, too much to choose from!!

You can keep your number no problems with a network change now, just takes a week or so to do the hand over.

Good luck
