SMS is dying...Enter MIM ( Mobile Instant Messaging)

Who wants to just text someone and hope they check their phone when you could instead see if your “buddy” is online, contact him directly if he is or see his away message is he isn’t, and then communicate via IM instead of SMS, which hypothetically means you are communicating over your data connection rather than paying per message with the SMS model.
But the switch is not that seamless.It has got some hurdles too...
Problem 1: Not everyone can get an IM on their phone, and not everyone uses the same service!
Problem 2: Using IM isn’t necessarily cheaper than SMS You’d love to think that delivering an IM from your phone would stream over your data connection and not use your limited SMS cache. But if you are a user in the states, you would be wrong! Both T-Mobile and AT&T deliver your IMs by basically texting. Each IM counts as a message, both outgoing and incoming, so that chat you just had with your friend for 15 minutes about Miley Cyrus just cost you 30 text messages.
Problem 3: IM is not any easier to use than SMS

Difference between VGA and Mega Pixel camera

VGA differs from a mega pixel by picture size. as we all know by now, VGA stands for a picture that's sized at 640x480 pixels. multiply those two, and you get 307,200 pixels (or 0.3 mega pixels). mega stands for million so a mega pixel means a million pixels. for example, a camera that can generate a picture size of 1280x960 without the use of interpolation can generate 1,228,800 pixels, or 1.2 megapixels; they just round it off to make it 1.3 mega pixels. some phones like that are the S700i, W550i, and the K600. camera phones like the K750i, W800i, and the W900i can generate pictures with a size of 1632x1224 (again without interpolation), hence producing 1,997,568 pixels, or 1.9 megapixels. again, they just round it off to make it 2.0 mega pixels...
