O2

Been an online customer for 4years with O2, on average spending £30-£35 a month. My contract is up in 3 weeks and the only phone i have seen that i liked is the new BlackBerry pearl. O2 has this for £49.99, which is fine.
When i phoned up they offered me 500minutes and 1000texts for £25, which is another £5 off my current monthly bill.
But when they went to offer this contract to me they said its not possible as the GPRS on the phone will not work if i am an online customer?!
They have told me that if i want this phone i will have to go instore and start a new contract with O2 store, which means paying £45/month for what i have now, which is a joke as i have been a customer for 4 years. I know their online and offline is seperate but it is just silly saying the GPRS wouldn't work, why wouldn't it if i can use the internet on my current phone?
The other option i have is to change operator, T-Mobile seem to have the best offers at the moment with their Flex tarrifs, i can get 500minutes and 1000texts for £30 a month and the Blackberry is free.
But what are T Mobile like for customer service and helping, and would the phone come with any branding on it, if so is it possible to get rid of it?

Thanks!

ps Another option could be going through online stores such as onestopphoneshop, but what are these stores like? a lot of them offer cash back but some people have said this is dodgy as they try anything to stop giving you it back

so by them saying it wont work, they are doing what? Trying to get more money out of me by making a new contract?
Just cant make sense of why they would say i wont work unless i am an instore customer
