Previously it was listed correctly as Singtel, but after I ran the Market Enabler app to download a US-only app it shows my carrier as T-Mobile. I have since rebooted my phone and restored default settings in Market Enabler and launched the Market app several times, but Android Market just refuses to revert my Carrier back to the original one. Is there any way I can force it to revert? Even after faking another carrier (Verizon), Android Market still shows T-Mobile. I don't know why - it's like it's taken a liking to T-Mobile - it just refuses to change from T-Mobile, although it has no problem changing to T-Mobile. Argh.
