What device and generation? Mine was at iTouch 2G

no, i have iPhone 3G but bro has ipod 2g i think

I got my first 12,000 wind on my iPod 2G. It isn't that bad.

yer my bro's isnt too bad he crashes quite a bit, but theres not much lag and it starts up fairley easily

I barely play on my iDevice these days, but here are some common logic solutions to reduce crashes

1) Make sure you're only running the one app and aren't Multitasking/Backgrounding any apps.
The iDevice has alot less ram to dedicate towards your app than say, on a computer.

2) As was mentioned before, disable image animations and sound, aswell as setting the 'font' to the simpler font (Less to render)

3) Stick closer to your access point.
The further away from your wifi access point you are the harder your iDevice has to work to keep up the connection.

4) Log out in your house or an area that is commonly quiet.
I have noticed that the most common time for the app to crash is when logging on. (Personally anyway) That is because the ipod is attempting to set up a connection with EVERY SINGLE CLIENT nearby at the same time.
Think about it, if you log into a quieter area, less connections to set up, meaning an easier job for your device.

Thanks Jatz :)

Crashing isn't caused by bad network reception, its more the devices inability to cope with the amount of data being handled so running only one app is the go but you don't need good network reception necessarily. 2nd gen iPhones/iPods are pretty notorious for crashing on era so if your device is 2nd gen or less then theres not really much you can do...

That is what i was kinda meaning, but i failed at explaining it. but the more free ram the device has, the more able it is to cope with the amount of data.

yer well the iphone 3g cant even multitask lol

:S yes it can, you have to be running ios 4 though

well then i dnt have it

Omg I have 2nd Gen iPod Touch... It always lags like hell.

i download the new system version and now it crash but less than old version...

Jatz I already had done everything on ur list. BUT IT STILL LAGS LIKE HELL

i wish there was an update that fixes it :(
