I recently upgraded by mobile to a HTC Touch 2 phone butI am pretty happy with the phone I already have and could do with the money following Christmas.
It looks a pretty good phone and speaking to the people in the t-Mobile shop they say it's very similar to the iPhone.
The phone is totally un-opened, I just received it today but I think it will be locked to t-mobile but I'm sure you can get them un locked pretty cheap.
You can get loads more information on the phone at http://www.gsmarena.com.
I'm looking for around £350, but would be willing to listen to any serious offers.
As I don't have a high rep score on HDUK I guess PayPal would be best, although I do have a good rating on ebay, username is cw82_uk.
Shipping would be about £10 but if it's any less I'll let you know and take it off the price.
Payment would be needed prior to postage.
