There's no way to undo it, as the update overwrites the old firmware. There's no real reason to remove an update as the updates add new features and increase performance, as well as allowing access to the eStore.
I would actually say that cell phone accessories are great gifts for uncles. Once, I gave my uncle a leather holster for his cell phone and he loved it. He shows it to me every time I see him and thanks me. Hopefully, he will update his cell phone soon though. Check the related links for some great cell phone accessories.
I doubt it. Maybe if you reboot the system, otherwise no.
Click the arrow which is undo on the status bar on top.
Your phone may need an update. You can go into your account to find out how to do this or visit your cell phone provider.
VERY! what ever you did undo it
The calls might be from your cell phone server. I get those a lot too but it might be from marketers trying to sell things and trying to get you a vote for someone but if you do not recognize the number you probably shouldn't answer it. But yeah it might be from whoever your cell phone server is trying to get you a update or something like that.
