I'll try to look it up right now, but you're looking for ASTRO25 CPS. Going to be RVNsomething.
EDIT: RVN4185 (R15 appears to be the latest version, RVN4185AJ, but there is also R16.00.00 (AK) and 16.01.00.00 (AL) listed as unavailable but will be shortly). On my MOL account, it says the earliest ship date for R15.00.00 is 27 Oct and "Available" is "N". Not sure whether it is available or not - I don't use MOL too often these days.
EDIT to EDIT: I just noticed that's ASTRO25 MOBILE. Not sure if portable comes bundled with mobile for them. RVN4181 is the portable version. AK is R15.00.00, AL is 16.00.00, and AM is 16.01.00 - same things apply as in the above paragraph as to availability.
