3G Internet from Cosmote - opinions, impressions, experience

After the launch of the iPhone 4 terminal through the mobile phone operator, many people asked and still ask how well the Internet works at Cosmote. The operator bought the Zapp company together with all its 3G telephony/internet infrastructure a few years ago and integrated it into its own network so that now all Cosmote customers use 3G internet on the old Zapp infrastructure. Until now I understood that the internet works quite well, but considering the network it is normal for it to be like this.

For now, there are few iPhone owners who use Cosmote terminals, so I don't have much information to offer you, but I ask those who have Cosmote and iPhone: How will the internet work in this network? I'm mainly interested in what maximum speeds you got, if it goes as well all day/etc.
