T-mobile obviously got the message: it retracted the 1GB limit of data usage on its "unlimited" data plan for the Google Phone announced on 9/23. It came under fire when T-Mobile first unveiled the 1GB limit. Instead, it now says in its fine print:

To provide the best network experience for all of our customers we may temporarily reduce data throughput for a small fraction of customers who use a disproportionate amount of bandwidth.

AT&T and Verizon Wireless still advertise "unlimited" data plan on phones, but tethered phones or data cards now have a 5GB monthly limit.
