I am uploading a slightly modified version of the 160by2 provider. Changes include
-140 characters limit (only 80 for international, but not implemented yet)
-Removes leading 0 (Domestic) or 00 (international) if any
-Checks if number begins with 9,8,7 or 6 (requisite for Indian mobile numbers and intl' calling codes for supported countries)
-First goes to http://m.160by2.com/index.asp?in=yes instead of http://m.160by2.com so as to save time.

Please test and comment if there are any bugs in this. I have tried only international sms to Kuwait. But it was not working (not the app's problem. something wrong with their site). So please check others and let me know if it is successful.

PS: i can't upload py file here. Also txt file is too big to be uploaded here, apparently (huh?). So i have zipped it and uploaded it.
