How can I dev 3.x apps for cydia

hi,
I am going to develop an application for cydia, which runs on iPhone 3.x. I have a pc with Ubuntu, and failed to built open tool chain following the linker:
Installation - iphonedevonlinux - Installation of the toolchain - Project Hosting on Google Code
is there any way else to built the developing environment? Thx!

There is actually, and I just got done writing a blog post on it. You can use the iPhone 2.0 Toolchain from Cydia and compile apps on the phone itself.
