PPCGeeks - HTC P4351/T-Mobile Wing Instant Messenger Program

Hi all. I just joined your community. Hoping to find what I'm looking for. I used to have a T-Mo Wing, my warranty expired and the phone broke. So the best offer T-Mo gave me was $350 for brand new Wing. I said "NO", and went to eBay and found an unlocked HTC P4351 for $210 (unlocked!!). But there is a problem with this device. It doesn't have that OZ Instant Messenger as the T-Mo Wing does/did. So I'm trying to find a free multi-client messenger just like that OZ Instant Messenger. But I want for it to vibrate when the PDA is set to vibrate mode. My OZ didn't do that. It only made sounds when my sound was on. Thank You people!!
