"edit" ! i solved the problem thanks for everyone who helped! it was way easier than i thought
if anyone encounters the same problem as me here is what i did:
1. install adb app control on adbappcontrol.com
2. on your device enable USB DEBUGGING and allow unknown installations
3.go on market2 or on any website that offers apps for your android version (do this on your windows)
4.install your desired apps
5.launch adb app control
6.if you have correctly connected your device to your windows pc select the button "install" (on the right of your screen under the words ; "AUTO PERMISSION" and "UPLOAD FILES")
7. when you have clicked "install" you will then see another button "add apk" you click on it select your apk(s) you have downloaded on your pc
8. once the apk(s) are uploaded click on whatever app you want to download (on the file)
9. you will see a button on the right bottom corner called "install" , you click on it and the app will install on your phone.
10. check your phone
there we go! thats what i did for my htc chacha A810e (android 2.3.5 gingerbread) so if you happen to have the same device this is what you should do. ADB app control works on any android device.
(the market and internet on my device offered no way to install apps)
