Has anyone tried this?

What is the deal with it? Does it work like Ramble?

Thanks.

did you download it? Is it any good?

I didnt download it cause im at work and have my blackberry hooked up from my home computer. If they had an on-air download I would do it.

it uses SMS not GPRS for messaging, so expect some potentially high bills if you chat a lot, unless you have an unlimited SMS plan (which they no longer offer, i don't believe)

tmobile no does havea unlimited text message though it does not just pertain to sms it also pertains to mms (picture messages) to its 14.99 on top of your current plan but is unlimited. i have it for my 7100t which i occasionaly mms from but not to much though i do heavily text this is a bonus. which i am about to unlock and TRADE my 7100t to someone for a preferably 7290 unlocked or tmobile or a 7280 unloacked or 7230 locked or not. any one intrested.

If this is the same application that comes pre-installed on the 7100t, it is garbage. Takes forever to get or receive an IM. The lag is so bad that you can't have a normal conversation with anyone.

Note: The Instant Messaging application for the RIM 7290 will not work properly if loaded onto other RIM devices.

On my 7230 it filled up my sim card with messages. When I removed it, it cleared them up.
