mod_alias's RedirectMatch would work.

Query Strings
The Query String, also known as a Parameter, is the part of an url after the question mark. Question = query.
By default, rewrites simply ignore the query string. That is, mod_rewrite stashes the query in a safe place, does its stuff to the part before the question mark, and then reappends the original query.
Changing a Query
#1 To delete a query, add a ? to the end of your rewrite target.
#2 To replace a query—or create a new one—add ?blahblah to the rewrite target. The blahblah can be either literal text, or stuff you captured earlier. (#1 and #2 are really the same thing: you're just replacing the query with either something or nothing.)
#3 To add to an existing query, again put ?blahblah at the end of the target, but also add [QSA] to your flags (the bracketed items at the end of the Rule). It stands for "Query String Append", meaning that the blahblah is to be added to the existing query—if any—instead of replacing it.
Getting the Query
You only need to retrieve the original query if
#1 you want the rewrite to behave differently depending on what the query was
or
#2 you need to change or delete the query
Add a Condition that says
RewriteCond %{QUERY_STRING} blahblah
using your ordinary Regular Expressions, anchors and ! as needed.
To test whether there was a query at all
RewriteCond %{QUERY_STRING} .
which simply means "If the query contains at least one character of any kind".
If you need to capture any of the query, use parentheses as usual. In the rewrite target, the captures will be %1, %2 etc instead of $1, $2 etc, because they are coming from a Condition instead of the Rule. Each set is separately numbered, so the first capture from the Rule will still be $1.
I can't seem to get it working. I'm interested in finding out what is stored in the QUERY_STRING. Is there a quick and dirty way to do it?
It just seems like the Rewrite is not removing the "?" from the url.#1 To delete a query, add a ? to the end of your rewrite target.

RewriteRule ^(.*) %1 [QSA,L]
and this is the resulting url I get: http://example.com/iphone?/iphone
So what am I doing wrong?
but, im not able to go EXTENSIONLESS
