I can't install most of the games on my iphone 3gs ios 4.1?

My brother got a samsung galaxy s3 and all the games works fine on his mobile so he gaved me his old iphone 3gs and i tryed to make it better i went to the itunes to install a new ios and i make it worse. I send it to some1 who can fix it and he did fix it and installed ios 4.1 on it but when i try to install games on it it says… This game need ios 4.2 or 4.3 or better please i need a way to play my games on it i tryed to install 4.2 and 4.3 but didint work. And i can't buy a new iphone if i can i would buy. Please i need help so i can any app i want. I'm not asking for the ios 5 and 6 apps just 4.2 4.3 please <3 i was happy when my brother gave it to me but when i tryed to install my first game it won't let me. P.s i can install games like pes 2010 but i can't install games like where is my water or angry birds.

Um, just upgrade to ios 6. Iphone 3gs still has that option.

Most of the games will not work on iOS 4.1 so if I were you I would upgrade to iOS 6.0 or higher so you can play at all of the game

Just like with Android users who still have a Android 2.2 OS phone… When devs make new games or update their old games, they will make a requirement for the game to only run on modern OS builds… These means, for androids, you must be on Android 2.3+… For Iphones, you must be on IOS 4.2+… Technically IOS 5+

also… When you install a modern new IOS or android update on a OLD OLD OLD phone, IT WILL MAKE IT SLOWER… Facts of life! This is why your dude put 4.1 on your iphone, cause your Iphone was made for 4.1… A 3GS was not made for IOS 5 or IOS 6… And DROID X was made for Android 2.2 and 2.3, not Jellybean 4.2! IT will make it slower and worse… The old phone RAM and CPU can't handle the new OS requirements!

your fix---
1) deal with it
2) rip open the phone and custom install an A6 processor and a 1 GB RAM, then re-write IOS to except the new chipsets
3) find away to install IOS 4.3 or IOS 5 and STAY THERE! If it gets slow---deal with it

not trying to be mean… Just educating a non tech in blunt words

If you actually want to get any good apps, you will have to upgrade to iOS 6. You said that by downloading the new iOS it made it worse… How so?
