The flashing worked for me. I had a Starhub branded black 64GB (Singapore 059L3V7). Just like Drekkie (earlier in the thread), I successfully debranded it by flashing with the Central Europe PR1.1 (DFL61_HARMATTAN_20.2011.40-4_PR_LEGACY_001-OEM1-958_ARM.bin). It's been a couple days so far since I did the flash and I haven't noticed anything strange. Thanks!
