Hi my 1st post on this forum. I'm a long time Blackberry user and thought I'd post this as it may be of some help. My contract was up yesterday with T-Mobile (UK) so I went into their local shop with the intention of closing my account. Well they offered me a brand new 8800 for nothing! and kept my existing (cheap) deal.
All great apart from the fact I couldn't get the internet or BB Maps to work tried all and I mean all the suggestions posted here then called T-Mobile a very helpful guy updated my account to include BB mps etc and hey presto it all works I've not had to make any changes to APN's, Ports or anything very pleased.
Latest update at the moment Opera mini and Google maps don't connect at present
