So does that mean that the T-mobile wifi hotspots are not safe either as i
was about to sign up for it?

Tony,

Free/Open WiFi networks are inherently less secure than wired networks
because of the way the data travels. Instead of packets being sent over a
wire they are sent out into the air. When packets are sent over a wire one
must be either connected to the network transmitting the packets to see the
packets or have physical access to the line and place a sniffer on it. When
packets are sent over the air anyone in range (and the range can be pretty
large depending on the type of antenna) can see all the packets. There is no
longer a need to be connected to the network. So basically, anything sent
clear text can be read by those around you. This is especially true in
crowded environments such as airports or coffee houses.

I think it's fine to use Public Wifi for a connection to the internet, it's
just necessary to realize that anything you type in can be read by the
general public.

As long as you transmit public information, you're fine. I wouldn't,
however, transmit sensitive information in such a fashion.

Hope this helps!
