If you activated via iTunes with a valid carrier sim, then (generally) you don't need hacktivation.

limera1n uses the same hacktivation dylib as blackra1n RC3 used.

Limera1n installs hacktivation no matter what, that can interfere with later attempts to activate the phone legitimately via iTunes. This is one of the reasons I have avoided recommending blackra1n as your primary jailbreak. The same advice extends to limera1n.

Back to the topic of the thread. Wifi staying on is a feature of iOS 4.x and is not exclusive to the iPod touch. It should disconnect from wifi after 30 minutes of standby.

Olethros,

Thanks a lot for that explanation, it's very clear now.

Thanks

Apparently something's wrong with Apple push notifications: they kept my wifi on even after locking the iPhone, even if I had them set on OFF.
I'm 100% sure that's the problem (at least for me) because i deleted the push notifications daemon (located at /System/Library/com.apple.apsd.plist), restarted and now the wifi goes off automatically when sleeping.

Skler000,

As Olethros mentioned and as i suspected this does not look like a problem but a feature of iOS 4.1

Perhaps it's related to facetime being on?

This is actually a good point. Facetime keeps push notifications active even when they have been turned off in the settings app.

However I am sure that the wifi staying on for 30 minutes after the phone is put to sleep is a new feature of 4.1
