Gsmtool Is Online

After mac2vendor another old tool that I made is back online on the new site. Gsmtool is back new and improved. This tool lets you lookup which operator a GSM IMSI number belongs to or list all the Mobile Network Codes for a certain Mobile Country Code.

The old version was based on information from Wikipedia, this new version uses information from the ITU and should therefore be a lot more accurate. Also, the previous version did not handle 3 digit MNC codes properly.

Also: Really, ITU, who on earth shares long lists of assignments in MS Word format?! But that aside… Luckily vi and awk are here to save the day.
