2,113 songs consuming 4.5GB, average file size of 2.2MB. I can fit all of my CDs on my phone with room to spare. At 64kbps, audio quality is (surprisingly) good enough for the car and listening with headphones.
Noticed that Opera Mini 6 is available for iOS now.
No achievement for me 🙁
Found out today you can show the battery percentage on the iPhone.
