But why? N-Starter itself can switch Bluetooth of the device and this can be assigned to one of its shortcuts. Why use an other application (even one which cannot create a shortcut for itself) and waste valuable memory for one more app?

I'd just go for the N-Starter, if only it behaved normally on my E61. (Mind you, trying to type in Alpha keys - with the blue key - and using the shift key for uppercase can switch BT or even reboot your phone!) Fortunately, E61 has its own bluetooth switch shortcut, and its built-in :)

mr, The application I'm talking about here switches bluetooth on/off without any prompts. You assign a shortcut to it, hit the shortcut and BT is switched on/off instantly. Nothing in between.

I believe without this app, N-starter will first launch the Bluetooth application then you switch BT on/off from it.

Well, your assumption is actually far from correct, as NStarter does exactly the same thing, directly. It switches BT on/off with just a shortcut click, no menus, no messages. I've used it with my E50 (which does not have a builtin shortcut for that). The app is surely valuable, maybe for running on startup (to make sure your BT stays up all the time) - i'm just creating use for it :))

I swear this doesn't happen on my N80 lol :D. Maybe maybe what your saying is only available in E-Series phones but honestly not in my N80.
Anyway, thanks alot for your feedback and Happy new year ;)
