Ahem... Stockholm and Oslo already did that while back. I do think they are part of what you call "the world".

It's even more funny when you take into consideration that Sweden was one of the nations proposing this directive.

This law itself, in it's current form, nullifies the newly passed IPRED law.
The law says that stored information can only be requested by the police or prosecutors if a serious crime has been committed (or the suspicion of a serious crime).
Hence a third party like RIAA cannot request information to file a suit according to the IPRED law.
Another law in Sweden, currently active, says that all identity information MUST immediately be DESTROYED when it is no longer required for completion of business transactions.

That's some fine politics there, Lou!

The data retention directive is to be implemented in law on January 1, 2010.
It was supposed to be implemented on March 1, 2009 but was postponed.

So why sue now when it's coming anyway?

Earlier this week the first 4G base station was installed in central Stockholm.

The next generation mobile technology (LTE) provides speeds up to 150 Mb/s.

here you can see a few other ISP's that erases logs.
This behaviour is not a circumvention of the IPPRED law but an enforcement of law of electronic communication that states that customerinformation that is not needed for daily operations must be erased as soon as possible.
This law in itself nullifies the IPRED law.
