I've been trying to set up Instant Messaging on my 7290, following the advice and settings posted on these forums, but without success. I contacted my carrier, Vodafone, to confirm the APN settings and enquire whether any additional data services need to added to my account, but they simply told me that they do not support such services and the BlackBerry is intended only for email(!)

Can anyone offer and experiences or advice?

Errrr....do you want to put this post in every section of the forum....don't waste space and bandwidth bro!!!!

Sorry, but two sections didn't seem OTT, given that the TCP issue applies to aftermarket software but not exclusively.
