Ahh ..I was wondering about this...i've talked to various T-Mobile reps and none of them seem to be able to give me a definate answer on whether the Yahoo Messenger and the AOL Messenger would be using text messaging or data (I have the 600mins/unlimited Blackberry Add-On but no free text message plan).
Is there any way I can be SURE I get the correct version's of these 2 programs so that it doesn't use text messaging (and thus cost me a bundle)?
