It’s been almost three months since the O2 MMS iPhone application moved to donation-ware.

I must say the outcome has slightly restored my faith in the shareware model

As of now there are 2,015 registered users of which 470 have donated, a 23% conversion rate.

The O2 MMS application has handled an incredible 12,700 MMS messages since launch

I gather anonymous statistics only (and obviously don’t go reading peoples MMS messages!) but one thing that I did implement out of curiosity was a checksum to see how many images were identical (e.g. forwarded MMS messages) - interestingly one image has recurred over 73 times around Christmas. Sadly, unless someone sends it to *me* i’ll never know what it was

Before anyone’s concerned that this actually compares their photos - it doesnt! - The checksum is based on MD5 so it is impossible to reconstruct original images from the 32 character string it generates, it’s just very unlikely that two images could generate the same checksum so it’s good for random facts like that
