Where do I find 3rd Party Apps?
Besides the market I would try contacting the dev of the app your wanting. I can only speak for myself but anytime anyone asks for one of my apps I will gladly give them a copy. I like to think if they like it they will support future development anyway. What can it hurt the worst they can do is tell you no.
I know there are websites where you can download them, I was just wondering what the sites are.
How do I make it so I can download apps not on the market? I keep getting blocked.. I rooted my phone, I have root explorer and sideload tried to download the apk but sideload froze my computer everytime. I tried with Linda as well but that didn't help still blocked.
My apps are under HLDeveloping in the market...I dont know what exactly your looking for but you can try other markets like slideme... If your asking for help to find a piracy site you arent gonna find much help in forums that tons of developers are members of,I wouldnt help you and dont know many who would. What is it exactly your trying to accomplish?
Oh ok I see very sorry thought you were just interested in pirated apps... I hate that at&t does that its not really an android thing at&t wont allow the phones unless they lock them down like this they are the only company I know of doing it I could be wrong on that though. Have you checked the Captivate Bible to see if there are any answer's to your questions there?
I think to efficiently sideload apps you prettymuch have to be rooted for the Captivate again dont quote me on that but from what I read thats how it sounds. Let me know if I can help at all.
