We've yet to see Palm or Sprint confirm these numbers, but a quote from JPMorgan found in a Wall Street Journal roundup this morning asserts that "sales [of the Pre] in the first two days probably exceeded 50,000." The report continues by mentioning that said figure was "aligned with expectations, but probably fell short of the 146,000 reported first-gen iPhone sales" during its opening weekend due to "capacity constraints in manufacturing." By and large, most analysts are deeming the Pre launch a success, though it's hard to say whether the suits at Palm and Sprint agree or disagree. No matter how you slice it, 50,000 units in a single weekend ain't nothing to scoff at, but we'd say next weekend's sales could be even more telling. You know, if anything goes down today at 1:00PM ET.
