hey everyone, i bought my 1st iphone recently so now i want to explore possibility of this stuff. time for some app to communicate with other people for free/lower costs. most of my friends are using whats app or vippie. i think vippie is better, cuz you can call other users and even normal numbers, while whats app is created for instant texing. what do you think? any of you have ever used/heard about both apps? which one is better? i found vippie on facebook  ( https://www.facebook.com/pages/Vippie-India-Unlimited-Free-Calls-Free-Messages/630904443604080?fref=ts ), but its hard to find more info about on internet. can you give me some websites/reviews?
