Here are my fave apps:
For chat I'd recommend...
Palringo or Palringo Lite. I use Palringo Lite as I find that is enough and the full version isn't necessary. Palringo Lite is free and there's a small fee for the full version.
Facebook - if you have Facebook this is the perfect free app for you!
Games...
Flick Fishing - a fishing game which is fun for all ages. Although you look a little weird while casting the rod! You have to flick your wrist! I believe this is 59p.
Tap Tap Revenge 1, 2 and 3 - all games are very good! This is a bit like guitar hero, you tap buttons to the beat of your favourite new songs! Often songs that are in the chart. All of these Tap Taps are free, but if you want extra tracks other than the free ones you may have to pay - although not for all!!!
LeafTBone - it's like you're playing a trombone but it looks like a leaf hence the name. You play songs which are submitted by other players...there's loads to choose from! This costs 59p.
Tap Studio - it's a bit like Tap Tap Revenge but you can use songs from your ipods library. There's a free and full version, I only have the free version and it's very good!
Guitar2 FREE - you can either play as guitar or drums. The free version only comes with one song buut you have to pay for the full version.
Guitar FREE - it's the same sort of thing as Guitar2 Free.
!Park It! LITE - You have a steering wheel and a throttle, you have to park your car!
Rollercoaster Rush - you have to guide passengers round a rollercoaster without crashing. There's a frree and a paid version.
Waterslide - you have to steer down a waterslide!
Airport Mania - You run an airport and you have to guide the planes. 59p.
Papertoss - you throw paper into a bin. Sounds boring but it's actually very good! Free!
Fieldrunners - you have weapons and you have to put them in strategic spots to kill the enemy. Free.
F1 '09 Game - You have a large choice of tracks and drivers. £4,99 - but it's worth it in my opinion!
Puzzles...
UnblockMeFree - it's difficult to explain but you have to free the red block. This is a free game.
ML Quiz Lite - this plays you songs from your music library and you have to identify them. This version is free but there's also a full version which you have to pay for.
Idiot Test 3 - it's a funny test which you can give to your friends with fun questions to see if they're an idiot.
Bejewled 2 - a very well known game where you have to move crystals so they are with matching crystals. £1,79.
