If it wont let you delete it as described in the above thread, then it's probably not an app, but a link, which also means that it takes up little to no space. You could just hide it.
Wait. e-Mobile Weather is definitely an app. It is not a service
book pushed icon, so hiding it is pointless as it is still taking up
much more memory than a simple icon.
You can remove it one of two ways:
1) Options > advanced options > applications > scroll to the app >
press menu and select delete. You may be required to restart.
2) Open Desktop Manager > connect phone > click Application
Loader > click Add/Remove > take the check out of th box
for the app and "next" your way through to remove.
