folks, just happen to find the difference between greenpoison and limerain, although i don't exactly know what causes this considering the exactly same exploit being used... even the dev team has been numerously clarifying that no difference except on the loader (the program in your computer that is used to inject the exploit to the idevice). Nonetheless, i've been restoring the same ipod a couple times, changing from GP to LR and otherwise, to really prove my observation: Greenpoison loads Cydia blazingly fast... the difference is very obvious when you click on Changes button. GP needs no more than 5 secs in my wifi network while LR needs a couple of minutes, often more than 5 minutes. On the other hand, GP causes crash on youtube when you download a certain movie with Yourtube 2, while the same video plays nicely in LR. I've personally tested this!! for instance, just search for "gamaliel kbidols" in youtube app. you'll be presented by a single result (namely Gamaliel & Audriey Tapiheru - Medley bla bla bla), and try to download this video with Yourtube 2. after the download completes, try to watch it directly with Youtube app by clicking on the video. Youtube will crash in my device jailbroken with greenpoison, while the same device doesnt crash if i jailbreak it with limerain. i know yourtube is being updated at the moment as people mentioning these crashes everywhere. But strangely limerained device doesnt exhibit the crashes. Please do test this and post the result. For your ref: my device is 32GB iPod Touch 4G. thanks.
