does any one else use IM+? im using it... well when it works... lately it wont connect and right now i get the error cannot open tunnel... but anyways something else was wrong with my handset because it would just turn off when it wanted to i have the 7100t and tmobile is replacing it and giving me the 7105... is there any big differences from 7100 to 7105? and with IM+ is anyone having the same troubles? please let me know asap.

Thanks
