My iPhone 3GS (yeah, the “fast” one) has been getting slower and slower since the iOS 4 update. Recently calls have come in without answer buttons popping up instantly. Whenever I call up the keyboard I can now type an entire sentence before seeing anything show up.
I have found something you can do to fix this…
- You want “Reset All Settings” – be warned that you will lose all of your setting information. Generally this isn’t much. You will forget your saved WiFi networks, and any Sound / Wallpaper settings etc. You will NOT lose any of your email account information, photos, songs, data, bookmarks, notes, or application information.
This helped me a LOT. Of course I did spend a minute setting up my old settings again.
I’m not sure if this works because after a while the “Multitask” bar gets extremely long or what. It just seemed like a big “Recently Used” applications bar to me.
