my phone was originally the HK firmware and i updated to EURO1. the fonts while different, don't make that drastic of a change. EURO1 font is slightly shorter but fatter than HK font.
the camera sounds coincide with the "warning tones" under your profiles. if you have the ability to turn camera sounds off, it would mean turning the "warning tones" off in your profile regardless of the camera sounds settings.
and to angelwing and everyone else having problems, i too tried to update the first time and it scanned for about 3-4 minutes and came back saying no update found. i clicked retry and within 2 seconds, it asked if i was willing to accept their TOS and continue with the update. my phone was originally HK flashed to EURO1 and the updater flashed to the newest EURO1. so far, so good with nothing missing and the text message is lightning fast. i just updated to the 0.3 2 weeks ago, so i know what a freshly clean version of text messaging is like and this time, it beats it hands down.
