Yohanes Nugroho is at it again with a new version of his original LocalBar app. The new LocalBar app gets around RIM’s block of the original LocalBar app method by using a proxy to fool the PlayBook into thinking an app is being sideloaded from a PC. Yohanes has provided a proxy that you can run on your BlackBerry smartphone on the same network but you should also be able to do it with any proxy software on your desktop (tinyproxy, etc), router, or other smartphone like Android (Proxoid) devices.
I really wish RIM would just allow direct app downloads on the PlayBook but they seem adamant on maintaining strict control of app delivery. Until then I highly recommend checking out Yohanes’s new LocalBar 2 app. You will still have to sideload the LocalBar 2 app the regular way using a tool like DDPB or directly. The irony is that you can also use the LocalBar 2 app to sideload apps from one PlayBook to another without a proxy but not from one PlayBook to itself without using a proxy.
Check out LocalBar2 directly from Yohanes here and let us know if it works for you! Make sure to download the LocalBarProxy app to your BlackBerry from the same page if you want to use your BlackBerry as a proxy.
