Whatsapp for UK
Funny you should ask...my UK friend asked me to add Whatsapp to my iPhone at 4 today. I added it, turned it on in settings, and within minutes I not only was texting my friend, but I sent a picture of me sitting in the chair doing it.
My friend has a Blackberry, but this app is for iPhone, Blackberry, and Android. She and I texted back and forth for about 10 minutes and it allows you to add emoticons. .99 cents...great deal.
Yes...it works just great. The app goes into your contact list and shows your UK contact's number. You just write the message. The app does not allow calling free, so don't accidentally hit the Call button...I did and my friend's cell phone rang.
