So there's nothing I can do to be able to download applications ?
Correct. Since your the highest IOS on your phone is 4.2.1 and you need to 4.3 to download you can't do it. There no way around it unless you upgrade your phone. Period.
Thank you all for your help
YOur welcome. IF the app you want to use is facebook, you can always log on using safari.
The only thing you can do to be able to download apps that require anything higher than 4.2.1 is buy a newer phone.
