i have verizons 188.8.131.52 os and i download the new v2 beta of instango and it works great. Sweet looking. Some people said it is a battery drain but i haven't noticed that yet. Never crashed and never disconnected so for no it shows great potentia. I never used jive talk. i bought im+ but this is way cooler looking than im+ because it uses avatars and other graphically inticing stuff.
