im havein that same problem on 3G iPhone. I cant install anythig over cydia,it gives me "reload" option where it sholuld be "install" but over Icy i can install it just does not work soo waiting for some news on fix.. Good luck to us all
I have the same problem but I managed to repeat the process. Pwnage Tool v3.0 consistently jailbreaks/unlock my 2G phone. It is in the step process where we install third party apps where the problem lies, so to be clear.
1. Firstly, Open settings, enable wi-fi to connect to the internet, tests all the iPhone apps, Open Settings, Open iTunes, App store, etc. and see if everything is good. Do not open Cydia until you are happy with the iPhone apps are working. If everything is good, then go to next step.
2. Open Cydia. if you are able to load Cydia and see "Welcome to Cydia", the gate is open but no cigar yet. Scroll up/down to select "Featured package", install Winterboard (everybody likes that). Exit Cydia and tests the Winterboard, select a wallpaper you like in Settings. open Winterboard and select "User Wallpaper". press "Home button, this should reboot the iPhone automatically...wait (don't panic!) Then open Cydia and press "Changes" to update, if there are? Make sure Winterboard is working and the tests the rest of the iPhone apps.
The last post helped me after I had a "Reload Springboard" loop on my 3G, though a few odd things are still happening:
-Cydia's icon is just a grey box
-Reloading Springboard takes a while (few extra seconds of blank black screen)
-AdBlock doesn't work (Most certainly hasn't been updated)
Hey guys,
Believe me when i say that i tried everything to get the cydia update loop thing to stop. Attempted what the previous reply said about using winterboard first and then attempting the updates... still no luck...
However, i tried jailbraking with redsn0w and i have had amazing results. I can update everything on cydia no problem. Maybe it was something that the custom firmware option was doing, but simply installing cydia through redsn0w i think is what everyone should try who has had my problem.
to salvatore943 im having the same problem i just unlocked and had my iphone jailbroken yesterday and everything was going fine. then i try and go on cydia this morning and it says i cant connect to the host. then it just closes and goes to the home screen
