I am currently on Orange, planning to migrate to O2 for iphone 3G sake. After getting my PAC from Orange, I was hopping to buy my new phone from my local shop. I might wait a day or two though for those keener than me to have their go first. I was just wondering about coverage and general customer service on the O2 network. I have been with orange for over 10 years, so I am a bit nervous about the switch. I am thinking on going either for the £35 or the £45 per month option. They both say they offer 'unlimited wi-fi and data'. Does that mean I can browse the net, use weather and GPS and read/write emails all inclusive? If so this is really appealing. Any help? Thanks for your help!
