If buying a multi-functional smartphone is on your to-do list, you might want to wait a few months.

Apple, Google, Palm and RIM are all planning to release new phones starting in June.

Here’s a quick look at what’s coming, courtesy of the Silicon Valley Insider:

Palm (Sprint) - Promised the Pre by end of June with an estimated cost of $200 with two-year contract.

Apple (AT&T) - New iPhone announcement expected in early June with possible July availability. Could Apple drop price to $99?

RIM (Verizon) - Rumored to launch a new Blackberry in the coming months.

Google (T-mobile) - Speculation that scheduled T-Mobile event for May might reveal new Android-based phone or new Sidekick.

And there’s always the chance prices on older models will drop with these summer releases.
