One of the biggest pet peeves I have with Cydia is the constant refreshing that takes place. Not only does the app want to refresh after opening, it seems to also want to do a full refresh every time you add a source, or install a new app.
On my 3G, I probably spend over a minute just waiting to launch Cydia for the first time. Let alone the additional wait time if I am adding a source or new app.
Now, I'm sure this auto-refreshing is there for a good reason. However, sometimes It's just not necessary to do a full refresh. Until now, I had always wished there was a way to toggle this on and off.
Well now there is. iSpazio has released a toggle for SBSettings that will enable or disable the Auto-Refreshing performed in Cydia. This speeds up Cydia ten fold.
