One of the people I support has a 7750 that I recently upgraded to 4.0 for him. He complained of very slow performance after I upgraded him to 4.0. I realize that the 7750 is just slow generally but it seems even more so right now. I looked at the free space and it was about 20k so I cleared out his messages for him (606k) which sped it up a little. I was looking for other stuff I could clear out but didn't see much. Does the OS just take up that much more space or is there something I'm overlooking that I could clear to conserve large amounts of space?

The BlackBerry model 7750 is the slowest model of BlackBerry. To save more memory, uninstall unnecessary applications and OS components, such as uninstalling BrickBreaker and Password Keeper if you do not need these applications. Uninstall Phone if he's using it as a data-only device. Also, clear the browser cache as well, and make sure to reboot the BlackBerry by removing and reinserting the battery.

Yes, OS4 takes more memory -- the model 7750 is the one that seems to suffer the most from the OS upgrade.

Thank you very much Mark. Yes, it is very slow. I have one as well and am not that impressed. I would like a 7250 but it is not available through our corporation yet. I used to have a 7280 but had to give it to one of the execs I support.

Unfortunately, this particular executive I upgraded is also using his 7750 as his cell phone. I didn't think of clearing out the browser cache. He never uses the browser so I don't think it will help much. I will have to ask him if he uses the Password Keeper or BrickBreaker. Should I always reboot by removing the battery? I thought it was basically the same as pressing the reset button on the back. Thanks again.

I just find it easier to remove and reinsert the battery. No need to find a paperclip. Make sure that the proper kind of reset is the one that has the hourglass for 2 minutes -- not 15 seconds. (Under OS4, you don't get a full reboot anymore via the ++ three-finger salute, unless you do it twice, with a 15 second delay in between)

You don't lose data if you remove and reinsert the battery. Just make sure your email drafts are "Saved" first, if you were in the middle of composing an email and you need to reboot.
