Yahoo Messenger on your mobile phone using Yamee

I've been using Yahoo Messenger for chatting with my friends, working partners, and families. If no internet connection is present, you can try using it on your mobile phones. There are a few options such as Yamee, YmTiny, YaGo, eBuddy, etc. I haven't tried them all. The only one I tried is Yamee. And IMO so far Yamee is the best and free yahoo messenger application for mobile phone. You can download Yamee (the latest version I used is version 1.3) in here .

I have tried it on several phones, such as Nokia 6270 (GSM), Sony Ericsson K750i (GSM), and Nokia 2865 (CDMA) and it worked perfectly. Yamee supports a lot of mobile phones. You can check it on the above link. Here is the screenshot I captured from above link.

For GPRS connection settings in Indonesia, you can check these links :
