T-Mobile 3G Problems

Turns out that when you download an Adroid APK file from a web page and you're on the T-Mobile 3G network you don't always get the whole APK file. You might need to switch to a Wireless network connection to get a good download.

If you're trying to download a third party APK file like the ones I develop and you get an odd error that the package you're trying to install is replacing an existing package and this is followed by an installation failed message, you could be seeing this problem.

Some reports indicate you might also be able to get around this by switching to 2G mode, but I haven't tried it.
