HTC 8125 / 8100 / MDA (USA) / K-JAM / P4300 (Wizard)

I have had a Motorola V300 and you had to wait until the call was connected before you could activate the speakerphone. That was totally annoying. The best phone I've used as far as activating the speakerphone was the Nextel Motorola V66 - you could activate it immediately with a soft key.

I've read some of the reviews that seem to indicate people have used the speakerphone, so I am hoping that someone that has used it could help me out as to when you can activate it on this phone, especially if you're a T-Mobile user.

Thanks in advance.
