Hey guys, I've just got the x10 last week and was wondering which messenger app was good to use. I know BBM won't work outside of blackberry phones, so I went around searching what apps would work. I've found stuff like PingChat!, Kik, WhatsApp, TextOne...can you guys give me some advice as to which one is the most user-friendly and uses the least data? (I'm on a limited data plan). My main desire for a messenger app on the android is to send msgs to my friends internationally without paying for international text messaging! Please give me your opinions! Thanks!!!
