*This will, unsurprisingly, void the guarantee.
I think that’s carrier dependent, they’re slowly coming round to the idea that people actually want to do this. When I sent a rooted Galaxy back to O2 (with a letter asking them to replace it with something that wasn’t shit), they didn’t care that it was rooted.
I suspect that the remaining 3MB will be in the System partition rather than the Data partition so even if you could delete it the OS wouldn’t let you install anything else in it’s place…
Deleting its cache and updates will most likely be as much as you can do without rooting/etc…
+1.
An alternative is to install this.
We’ve done this in depth on STW before, but I’d be very sceptical of this sort of app. You can end up causing more problems than you solve.
In any case, you’re attempting to address a different problem. It’s akin to trying to free up RAM on a PC because your hard disk is full.
