Thanks for the guide using telet! far better than modmyg’s guide(s)

I think I now know the reason: according to this post at Luke Hutchison’s blog, “[B]ecause the .apk file is very small, if installing directly on the phone you must download the .apk over wifi, not over 3G, because a bug in the browser causes the file to get truncated a couple of kb short. The app installer in that case will say that it wants to replace “Android System”. Some info is here.”

Although he is referring to another app, this is exactly what happened to me with Telnet, and I suspect it’s the same problem. I thought I’d add this to the comments to help the next person who comes across it, or perhaps have it in the otherwise excellent instructions. I finally jailbroke my phone tonight using this.

I followed your instructions and I succesfully installed the ADP1 version of JFv1.31.
I just had to wipe all the data (alt+w in the recovery screen).

Thanks a lot

This is to be expected – press alt-L together as the article states.

Side: Thanks for this article James it was very helpful. Every step was very clearly written. I now have root access without experiencing any problems.

I reckomend to anyone that has root access to download the task manager fromt eh market place. It is very useful for closing unnecessary background apps.
