I use a Windows Smartphone (HTC s710). Few weeks back while attending a professional presentation I took down some notes and saved it in the SMS "Draft" folder. Today I wanted the text available in  my PC so that I can use the contents, I didn't want to retype the whole text (it was few SMS messages long). SMSing to my same number won't work & Windows Smartphone OS doesn't have a copy-paste option - had it got that I could copied and pasted it as an email.

Finally I found a way, I have a PCMCIA Internet Data Card in my laptop from Tata Indicom. I sent the SMS to that number, then opened the data card software which showed all the SMS (as seen in the right hand side image) in a textbox, I copied it from there.

Isn't this a neat solution?. Only drawback was that I had to pay for 4-5 SMS messages though
