I've released another version of MySpeed. I've fixed a few minor things, but the main change is to put adverts at the bottom of the screen. This also seemed like a good point to remove the beta label.
The adverts are from AdMob. Adding the little ad block was a piece of cake and couldn't have taken more than 15 minutes. I just followed the instructions in the readme and it was done. The API is well documented and even includes source code. A much more enjoyable experience than trying to use the Skyhook API as commented in a previous post. Also the ads themselves are unintrusive. Now we'll see if it makes a bit of money for me without pissing people off ;)
