I can't speak to cell phones, but it works on all "normal" browsers I've ever seen...

HTML 4.01 says:
action = uri [CT]
This attribute specifies a form processing agent. User agent
behavior for a value other than an HTTP URI is undefined.
The "uri" is a reference to RFC 2396, which says:
4.2. Same-document References
A URI reference that does not contain a URI is a reference to the
current document. In other words, an empty URI reference within a
document is interpreted as a reference to the start of that document,
[For some reason, the syntax does not allow empty URI
references. However, RFC 2396 has been obsoleted by
RFC 3986 which /does/ allow empty URI references.]
[And yes, the HTML spec should probably refer to URI
*references* rather than URIs...]
On the other hand, I seem to recall that it has been
rumoured that some have claimed that browser support
for empty action attribute is (or was) patchy.
I don't know.
