The Spirit Jail­break I used yes­ter­day on my iPhone to give me most of what I was excited about in OS4 with­out wait­ing for OS4 — back­ground music, home­screen wall­pa­per, home­screen fold­ers — also works for the iPad. And accord­ing to Mac­Sto­ries,

there’s a lit­tle trick you can per­form that lets you scale iPhone apps for the iPad, with­out wait­ing for the devel­op­ers to update their apps. In this way, and if you’re lucky, you can have an iPhone app run­ning in fullscreen with­out pixel dou­bling, which sup­ports all the var­i­ous ori­en­ta­tions and that even uses iPad’s UI elements.

This is huge. Lit­er­ally. Because after doing a lit­tle hack­ery — warn­ing, this involves remot­ing into your iPad via ssh and edit­ing the XML info.plist file for every app you want to alter — you can get some, but not all, iPhone apps to run as though native to the iPad’s XGA resolution.

Scale - Tweetie 1

They’ve already proven it works with Tweetie 2, and they have oth­ers ver­i­fied as well. Any­one with a jail­bro­ken iPad want to tell me if Stanza works with this? Because if it does, I have to scrape together some cash.
