Some operations on the Nokia E61 are painfully slow. For instance navigating the applications menu can be time consuming, especially if the folders being opened have many items in them. The other day I managed—by (un)installing some SIS files—to get the icon server of the device to crash (it produced a panic). This resulted in an iconless applications menu, with only application names visible, but otherwise seemed to have no adverse effect. And navigating the menu had become much faster, with no folder taking more than a fraction of a second to open.
The app menu navigation on Nokia E71, the latest Nokia crackberry, seems much snappier than on the E61, and incidentally the E71 icons also look simpler than the ones we’re used to seeing on recent S60 devices.
